The method to the driving engine usually with higher-wattage, thus also has larger engine blower, to provide the all-service vehicle of enough air circulation over-heat-exchanger especially effective.
Detailed description of the invention
Method according to the present invention is suitable for the vehicle of the power drive system comprised with driving engine, and this driving engine has cooling system and engine blower.Cooling system and power drive system control by electronic control unit (ECU), and wherein, this ECU can access the navigationsystem with terrain data.The ECU of Controlled cooling system and power drive system is well known in the art.
Navigationsystem can be to the operator of vehicle can with or as the black-box system only used by the ECU of vehicle, the satellite-based navigationsystem of any type.Although satellite-based navigationsystem is modal navigationsystem, but the navigationsystem based on any other type of other technologies also may use in the method for the invention.
Method of the present invention is based on the threshold value depended on for activating engine blower, and control the idea of power drive system, whereby, target is, keeps the temperature of driving engine and/or cooling system, makes to avoid the activation to engine blower.This will reduce the consumption of fuel of vehicle.
The first step of method of the present invention comprises the landform by using onboard navigation system to determine the route on the horizon of vehicle.Navigationsystem can from comprise commercial map map data base or comprise from the previous driving along route, the database access route information of road information of record.Other information generatoies comprised about the terrain information (that is, the change of height above sea level) of route on the horizon are just applicable to.
Based on the landform of route on the horizon, the load of driving engine is estimated.Based on the estimation load of driving engine, obtain the estimation to the temperature traverse of cooling system during route on the horizon.Because all parameters of power drive system are all known, therefore, such estimation is easily made and is well-known.Further, the method is suitable for using the load that affect driving engine and to the addressable all data availables of ECU, and such as, car speed, vehicle acceleration and in addition vehicle mass, if available.
Preferably, make load and Temperature estimate according to part, wherein, the length of described part depends on the landform of route on the horizon.Described part is preferably the section of route on the horizon, comprise relevant slope, such as one or more hillside, wherein, when the estimation temperature of driving engine and cooling system is the predefined value lower than first threshold, after descending, terminate a part is useful.
If cooling system reaches the temperature higher than first threshold in the temperature traverse of the estimation of any point, then calculate alternative power drive system and control, it makes the temperature of cooling system be maintained at lower than described first temperature threshold.Then, realize this alternative power drive system to control.
Therefore, the temperature traverse depending on estimation controls power drive system, and the actual temperature of cooling system during the route on the horizon of vehicle is maintained at lower than the first temperature threshold.
How this realizes obviously depending on landform on the horizon.But this can be realized by the speed increasing vehicle at stretch that is smooth or descending before going up a slope.Use the kinetic energy of increase of vehicle, vehicle can climb with lower engine load described upward slope, thus does not make the temperature of driving engine be increased to higher than the first temperature threshold.
Cooling system when first temperature threshold depends on that described fan is activated and the temperature of driving engine.But by making the temperature of cooling system be maintained at lower than this first temperature threshold, vehicle can be climbed lower than when described threshold value to make the temperature of cooling system be maintained at when activating engine blower.Due to the energy resource consumption person that engine blower is relatively large, therefore, because the power drive system changed controls, fuel is saved.
In the further embodiment of the method, power drive system is controlled, make during the route on the horizon of vehicle, the actual temperature gradient of cooling system is maintained at lower than thermal drop threshold value.Substitute and only check and temperature during the particular moment of time the gradient of thermal drop is monitored, rise to prevent excessive temperature after more than the first temperature threshold.If thermal drop is confirmed as too steep, then vehicle may have to reduce the load of driving engine during some part of route on the horizon, therefore, have modified the control policy of power drive system.
If the landform of route on the horizon is such, vehicle is just close to the peak on hillside, its descending is subsequently enough to cooling system is cooled lower than predetermined temperature threshold, then temperature threshold can be adjusted to peak temperature threshold value, it is greater than described predetermined temperature threshold.This is done to, when vehicle passes through the peak on hillside, allow the temperature raised a little of driving engine during the of short duration moment.By allowing the actual temperature of cooling system temporarily to exceed temperature threshold, ECU actively can avoid the activation to fan, and saves the energy.Allow higher peak temperature threshold value, because make it possible to carry out effective cooling to driving engine at descending on the horizon, because due to descending, reduce the load of driving engine, and still add the speed of vehicle, whereby, correspondingly maintain or add and make the air stream of driving engine and cooling system cooling and the flow rate of refrigerant fluid in a cooling system.
In the method, actual weather in the surrounding environment of vehicle and wind behaviour can be depended on further to the estimation of the temperature traverse of cooling system.By being used in the actual temperature in the surrounding environment of vehicle, will cause more failure-free prediction in the temperature traverse of prediction cooling system, wherein, method of the present invention will be more accurate.
The method can also be suitable for being used together with cruising and controlling.Realize method of the present invention by the control period that cruises in use, can the method be automatically performed.Equally, can limit or reduce cruise control speed is set, with the load on limiting engine, and thus thermal release.When using the method and control of cruising is not activated, if ECU can not control power drive system to controlling the identical degree that is activated with cruising, but, use firmly shifting gears downward or upward of in change-speed box or several gear and change-speed box, the moment of torsion output of limiting engine will be possible.
In order to make the temperature of driving engine and cooling system be maintained at lower than described temperature threshold, can arrange the torque limited of driving engine, wherein, the moment of torsion of driving engine is limited.Further, the fuel throttle valve of driving engine can be controlled, the actual temperature of cooling system is maintained at lower than described temperature threshold.The further measurement realizing the target of the method is the Shifting of adjustment change-speed box, and the actual temperature of driving engine and cooling system is maintained at lower than described temperature threshold.All that is measured, and (fuel throttle valve of engine torque restriction, amendment controls and Shifting adjustment) can combine to use respectively or mutually.
Such as, when the actual temperature of cooling system is close to predetermined temperature threshold, can initiate to change bottom gear.Change the more speed that bottom gear causes driving engine, thus the higher flowing of refrigerant fluid in a cooling system.Alternatively, can only route on the horizon landform instruction vehicle or be about at descending time, just initiation described in change bottom gear.Compared with there is the carrying out of higher car speed, descending period of advancing change the more speed that bottom gear causes driving engine.The more speed of driving engine causes the higher flow rate of refrigerant fluid in a cooling system, whereby, becomes more effective to the cooling of driving engine.During downhill driving, can further advantageously, activate engine blower, even if not yet reach described first threshold, this is decreased to making the temperature of driving engine further lower than the first temperature threshold.
As an alternative, the method is further comprising the steps: control driving engine, and make during close upward slope, the speed of vehicle is increased.By increasing the speed of vehicle before arriving upward slope, adding the kinetic energy of vehicle, wherein, can reducing, at the load of the period driving engine that climbs to going up a slope, to cause driving engine to the cooling requirement of the reduction of cooling system.
